Question 1

A distributed presentation client/server system is a solution in which the application logic, data manipulation and data layers are shifted from the legacy system to reside on the client. The presentation and presentation logic layers remain on the server (usually a mainframe.

Accepted Answer

In a distributed presentation client/server system, the presentation layer is on the client, while the application logic and data layers typically reside on the server.

Question 2

A distributed data client/server system is a solution in which the data and data manipulation layers are placed on the server(s), and the application logic, presentation logic, and presentation layers are placed on the clients.

Accepted Answer

A distributed data client/server system typically involves the server handling data storage and processing, while the client handles the application and presentation logic.

Question 3

It is important to understand the difference between file server systems and distributed data client/server systems. Both store their actual databases on a server. But only client/server systems execute all data manipulation commands to create, read, update and delete records on a server.

Accepted Answer

In file server systems, data manipulation is often done on the client side, whereas in client/server systems, the server handles all data manipulation tasks.

Question 4

It is important to understand the difference between file server systems and distributed data client/server systems. Both store their actual databases on a server. But only file server systems execute all data manipulation commands to create, read, update and delete records on a server.

Accepted Answer

In file server systems, data manipulation commands are executed on the client side, whereas in distributed data client/server systems, these commands are executed on the server side.

Question 5

A distributed data and application client/server system is a solution in which: (1) the data and data manipulation layers are placed on their own server(s); (2) the application logic is placed on its own server; and (3) only the presentation logic and presentation layers are placed on the clients.

Accepted Answer

This describes a multi-tier architecture where different layers (data, application logic, and presentation) are separated across different servers to optimize performance and scalability.

Question 6

The benefit of the distributed data and application client/server system is that by moving the application logic to its own server, that logic need only be maintained on the server instead of all of the clients.

Accepted Answer

By centralizing the application logic on a server, updates and maintenance can be performed in one place, reducing the need to update each client individually.

Question 7

A distributed data client/server system is also called two-tiered client/server computing.

Accepted Answer

A distributed data client/server system typically involves two tiers: the client, which requests services, and the server, which provides services, hence it is often referred to as two-tiered client/server computing.

Question 8

In a two-tiered system, the clients execute a minimum of the overall system's components. Only the user interface and some relatively stable or personal application logic need to be executed on the clients.

Accepted Answer

The answer of In a two-tiered system, the clients execute...

Question 9

Partitioning is the act of determining how to best distribute or duplicate application components (data, processes, and interfaces) across the network.

Accepted Answer

Partitioning involves distributing or duplicating application components across a network to optimize performance, scalability, and reliability.

Question 10

Duplication is the act of determining how to best distribute or duplicate application components (data, processes, and interfaces) across the network.

Accepted Answer

Duplication refers to the act of creating copies of data or components, not the distribution or allocation of them across a network.

Question 11

A network computing system is a multi-tiered solution in which the presentation and presentation logic layers are implemented in the client side web browsers using content downloaded from a web server.

Accepted Answer

In a network computing system, the client-side web browsers handle the presentation and presentation logic layers using content such as HTML, CSS, and JavaScript downloaded from a web server, making it a multi-tiered architecture.

Question 12

The same Internet technologies being used to build e-commerce solutions are being used to reshape the internal information systems of most businesses.

Accepted Answer

Internet technologies, such as web servers and browsers, are used for both e-commerce and internal business systems to improve communication, data sharing, and process automation.

Question 13

Network computing is a fundamental shift away from client/server computing.

Accepted Answer

Network computing is a distributed computing model in which applications and data are hosted on a central server and accessed by clients over a network. This is in contrast to client/server computing, in which applications and data are hosted on the client computer and accessed by the server over a network.

Question 14

An intranet uses Internet technology to integrate desktop, work group and enterprise computing.

Accepted Answer

An intranet utilizes Internet protocols and technologies, such as TCP/IP, web browsers, and servers, to create a private network within an organization, facilitating communication and collaboration among employees.

Question 15

In a distributed data client/server system everything runs in (or from) a web browser.

Accepted Answer

A distributed data client/server system can involve multiple components, some of which may run on servers or other devices, not just within a web browser.

Question 16

The programming language of choice for the application logic in network computing architectures is likely to be COBOL.

Accepted Answer

COBOL is primarily used for business, finance, and administrative systems, not typically for application logic in modern network computing architectures, which often use languages like Java, Python, or JavaScript.

Question 17

A distributed relational database distributes or duplicates tables to multiple database servers located in geographically important locations.

Accepted Answer

A distributed relational database system spreads data across multiple servers to improve access speed and reliability, often placing data closer to where it is most frequently accessed.

Question 18

A distributed relational database distributes or duplicates its database file servers across a number of transaction servers.

Accepted Answer

The answer of A distributed relational database distributes or duplicates...

Question 19

Data partitioning distributes rows and columns to specific database servers with little or no duplication between servers.

Accepted Answer

Data partitioning is a technique used to distribute data across multiple database servers, with the goal of improving performance and scalability. By distributing rows and columns to specific servers, data partitioning can reduce the amount of data that needs to be processed by each server, which can lead to faster query execution times. Additionally, data partitioning can help to improve data locality, which can also lead to performance improvements.

Question 20

When using replication technology the RDBMS must propagate updates from one database server to any other database server where the data is duplicated.

Accepted Answer

Replication technology involves copying and maintaining database objects, like tables, in multiple database servers, and updates must be propagated to ensure consistency across all replicas.
